Q: It says there is an inline check valve not pictured. Is there an adapter to hook directly into the sump pump. Also, I would be using this for a window well and having the pump submerged. Would this pump be ok for that use?
by Tara from Pennsylvania on May 01, 2014

A: Thank you for your interest in Sump Pumps Direct. The Liberty model CSP257 only includes what is listed in the product specs, which is:

•16.5" Wide x 15" Tall Perforated Poly Sump Basin
•Inline Check Valve (Not Pictured)
•24' x 1-1/4" Flexible Discharge Hose

The actual connections to the pump, would be provided by you, the customer, just like any other sump pump that we sell. For best results, a 1-1/2” male threaded X 1-1/4” barbed hose adapter will thread into the pump discharge. The 24’ flexible hose will fit over the barbed fitting of the adapter and should be tightened down with a hose clamp.

Q: I have a pedestal 10" diameter sump in a vacation home. The radon levels are marginal in the home. Would this pump kit csp-257 serve my needs for a submersible with hermetically sealed top???
by John R from Connecticut on November 30, 2012

A: The CSP-257 cover does have a gasket for sealing however there is not a 3” vent for the radon. You can remove the “blank” flange and add a K001392 (3” vent flange kit) which would be a special order item. You then would have to seal around the floor and basin with silicone, then mount the cover.

The pump is quiet, works, easy install after you dig(ugh) the hole. Read in other reviews that the hose was flimsy, so i hard piped it-- so far, so good.
Pros: Quiet, Easy To Use, I'd Buy It Again, Light Weight

I have not had to use the pump yet, but the kit was complete and appears to be of good quality (except the hose is pretty cheap, and difficult to fit over a barbed fitting if you cut the end off).
Pros: Quiet, Price, Easy To Use, I'd Buy It Again

First Impression
I will be installing this kit as a part of French drain in a crawl space. I plan to hard pipe due to reviews and length if discharge. Lady on the phone didn't know specific measurements of the lip. No biggie. One guy pulling and one standing on it we flexed it enough to get between joists. Pump seems heavier duty than the one from my old house. Looking forward to using it.
Pros: Price, Fast, Heavy

Csp-257 Crawl Space Sump Pump Kit
This is the second kit I have ordered from PED. The first kit was for my daughter's house and it arrived in 3 days and worked great. This pump is so quiet that I had to check the hose to make sure it was running. You can't hear it. The kit is great for the small space you have in a crawl space. It took me longer to put the electrical connection into the space than it did to dig the hole and install the entire kit. I was so impressed I ordered a second kit for my mothers house. This time... more

Great Quality & Price
This crawl space sump pump kit is great. They took all the guess work out of trying to figure out what pump to get with what basin. Compared with other pumps I've seen, (like the 6 month old one I replaced) this Liberty pump looks extremely well built as well. Installation was simple. Instructions were easy but not really needed.

Great Pump, Great Price
I looked at over 10+ sites on the internet and WaterPumpsDirect had the best price and most information I needed to make my pump purchase.

Thanks, the pump is going strong and have had no issues.

Good Pump & Basin. Hose Leaves Room For Improvement
Have had pump installed for about a month. It is working as designed. The hose has sprung a couple leaks. The hose seems somewhat tough but it is not. Just the little bit of movement from the pump kicking in has caused the hose to wear holes in its self where ever it touches anything other than dirt. It sprung a leak at the vent block hole I ran it out where it's plastic on plastic. It sprung a leak where it was touching the foundation footing as well.
Pros: Quiet, Fast, Easy To Use
Cons: Low Quality Hose

Great Pump Kit
After reading reviews, I thought this would be a great idea. At our summer home, we have standing water in the spring time so we installed this pump and put it on a timer with in two days the yard was dry the grandkids could play without getting wet best thing ever would recommend this kit to all very easy to put in and run the hose. THANKS!

Powerful Pump
I replaced my home depot pump (sensor corroded within 2 1/2 yrs) with the Liberty 257 pump. I called the very helpful representative for suggestions with my application. The pump arrived within a few days.

First, the pump is NOT imported. Second, this pump is much stronger than all previous 1/3 HP pumps. They tell you to limit the vertical height for the drain pipe. I modified this by installing a pair of 45 degree fittings to offset the original 90 degree turn. This reduces the hammering... more
